Technical field
Utility model relates to a kind of electric controling element, is a kind of adjustable time-delay Locking device that is used for contactor specifically.
Background technology
A.C. contactor is a kind of electric controling element that is widely used in the electric loop.Basically in all, can both find its figure in the low-voltage electrical power distribution cabinet.With the electric contacts of petrochemical industry electric power in learn, the double-cricuit supply that they use need carry out that electric power loop is cut conversion fast or when used power supply is subjected to external action to produce transient voltage fluctuation, decompression, and we need a kind ofly can keep the holding device that contactor does not disconnect in the circuit in the regular hour.Adopt when the general user tackles the loss of voltage, fluctuation at present: 1, condenser type timing contactor; 2, bayonet type contactor.From operating position, the condenser type timing contactor is reliably relatively poor, because of electric capacity itself exists factor affecting such as variation withstand voltage, aging, current/voltage.And the bayonet type contactor need add the protection loop, and control loop is complicated during use, also need provide ups power simultaneously.When ups power has problem, use the contactor of this power supply influenced entirely.These two kinds of contactors also can't be selected on drop-away time, adjust.Can only when dispatching from the factory, set, make the user that limitation is arranged when selecting drop-away time for use like this.Add that time control is to satisfy by electric energy, so be subjected to the influence of electric current, voltage in the time control easily.
Summary of the invention
The purpose of this utility model provides and a kind ofly can keep the adjustable time-delay Locking device that is used for contactor that contactor does not disconnect in the circuit in the regular hour when power supply is subjected to external action to produce transient voltage fluctuation or decompression.
The adjustable time-delay Locking device that is used for contactor that the utility model provides, the housing of this Locking device can be connected as a single entity with contactor, and this Locking device comprises: the delay line loop mechanism that is used to provide kinetic energy; Be used to store the stored energy mechanism of the kinetic energy that the delay line loop mechanism produces; Control, be used for opening and pinning the lock pin opener of contactor by stored energy mechanism.
The delay line loop mechanism comprises time-delay coil and time-delay coil armature, elastic energy accumulation mechanism comprises energy storage driving wheel and energy-stored spring, the outer end of time-delay coil armature has the time-delay bayonet lock to cooperate with time-delay fixture block on the energy storage driving wheel, thereby the lock pin opener comprises driven pulley, the dialling the lock tooth bar and can stir the shift fork of opening lock pin by dialling the lock tooth bar by driven pulley control that cooperates with the energy storage driving wheel, lock pin one end stretches out outside the housing, and the other end is pressed closer by spring.
Also be useful on the Locking device and regulate lock pin open-interval time-delay damper regulation mechanism, described governor motion comprises damping gear that cooperates with the energy storage driving wheel and the time-delay adjustment screw that cooperates with the damping gear.
This Locking device also has separate winding, can stir the separation finger that shift fork is opened lock pin thereby the armature outer end of separate winding has.
The utility model can keep in touch device and be in attracting state under voltage fluctuation, loss state in the time of setting, when voltage recovers, guarantee that contactor need not to restart can normally enter operating state, and can select on drop-away time, adjust.Owing to adopt machine driving, in use can be non-maintaining for a long time and can use repeatedly, the utility model is except carrying out under normal operation the energy storage, under outage, instantaneous loss of pressure situation, the time-delay all-pass is crossed the mechanical type elastic energy accumulation and is discharged kinetic energy and finish delayed releasing work, need not any power source.After the contactor energising, when the utility model is just started working, and contactor just pins by machinery, and contactor need not to switch on for a long time adhesive, good energy-conserving effect.

Fig. 2 is the vertical view of Fig. 1.
Embodiment
With reference to Fig. 1, Fig. 2, the adjustable time-delay Locking device that is used for contactor that the utility model provides, the housing 1 of this Locking device can be connected as a single entity with contactor, and this Locking device comprises: the delay line loop mechanism that is used to provide kinetic energy; Be used to store the elastic energy accumulation mechanism of the kinetic energy that the delay line loop mechanism produces; By the elastic energy accumulation mechanism controls, be used for opening and pinning the lock pin opener of contactor.
The delay line loop mechanism comprises time-delay coil 2 and time-delay coil armature 3, and described elastic energy accumulation mechanism comprises energy storage driving wheel 8 and energy-stored spring 6, and the outer end of time-delay coil armature 3 has time-delay bayonet lock 5 to cooperate with time-delay fixture block 4 on the energy storage driving wheel 8.Time-delay bayonet lock 5 is fastening and can be used for regulating by bolt 5.
Thereby the lock pin opener comprises driven pulley 13, the dialling lock tooth bar 11 and can stir the shift fork 14 of opening lock pin 15 by dialling lock tooth bar 11 by driven pulley 13 controls that cooperates with energy storage driving wheel 8, dial lock tooth bar 11 and be contained in 12 li of sliding seats, can move forward and backward, lock pin 15 1 ends stretch out outside the housing 1, the other end is pressed closer by spring 18, and the briquetting 19 of unblanking that cooperates with shift fork 14 is arranged on the lock pin 15.
Also be useful on the Locking device and regulate lock pin 15 open-intervals time-delay damper regulation mechanism, described governor motion comprises damping gear 9 that cooperates with energy storage driving wheel 8 and the time-delay adjustment screw 10 that cooperates with damping gear 9.Regulate time-delay adjustment screw 10 scalable device delay times, but such as the setting-up time shelves be 0.5 second, 1 second, 1.5 seconds, 2 seconds etc. four opening time point so that the user selects for use.
This Locking device also has separate winding 17, can stir the separation finger 20 that shift fork 14 is opened lock pin 15 thereby armature 16 outer ends of separate winding 17 have.
The utility model is reserved lock pin 15 functional interfaces at contactor armature place in use, and this interface is used for mechanical delay Locking device control contactor operating state.The lock pin of reserving 15 interfaces do not influence a contactor technical indicator and performance.Time-delay coil of the present utility model and contactor main coil are controlled by same circuit, switch on and off simultaneously.
Operation principle of the present utility model: after the energized, contactor main coil energising adhesive, time-delay coil electricity adhesive in the delay line loop mechanism simultaneously, time-delay coil armature 3 pulling energy storage driving wheels 8 make energy-stored spring 6 enter the energy storage state, driving driven pulley 13 simultaneously makes and dials lock tooth bar 11 and move and unclamp shift fork 14, lock pin 15 is subjected to spring 18 effects by the protruding pinning contactor of housing armature, and contactor keeps attracting state.Time-delay this moment, timing part have had energy source, and when delaying time coil 2 under attracting state, energy-stored spring can't discharge kinetic energy, and mechanical delay, timing part can't be worked.Under the state of time-delay coil 2 and contactor while dead electricity, energy-stored spring discharges kinetic energy, open the lock pin funtion part and pass through transmitting gear by former setting-up time in time-delay, timing, operations such as time timing damping wheel, time opening lock pin 15, to the release of contactor armature, contactor is threaded off get back to unlatching, off-state.When needing, when pressing separate winding 17 section breakers, the armature 16 of separate winding 17 is connected adhesive, also can open 15 pairs of contactor releases of lock pin immediately.
